Hi Eric, I have a 2013 XStar with the 7.4L ilmor. I just recently bought it used and it currently has an OJ 4 blade 14.75 x 17.5 prop. However, I live in Denver and our lake is at almost 6000 feet elevation.(Definitely, High Altitude) We only surf, anwill always have the boat heavily weighted with people, ballast and the Plug N Play ballast system. What prop do you suggest for our XStar based upon the info I provided?

Eric,
We have a new to us 2007 MasterCraft Maristar 230 VRS. MCX 350hp motor. No tower, or ballast, yet Should have a tower next year. Ballast-TBD. We slalom, and now that we have our first V-Drive, we are trying wakeboarding and wake surfing. The prop is the stock OJ 14.25 X 14.5. Looks like it has been repaired a time or two. Do you have a recommendation/price for a replacement? The original can then be our spare. Thanks much,
Steve

P.S. Wakemakers has a OJ 475 14.25 X 14.5. $549, after military discount, $500. Is this the best prop, or is that a newer model? Thnxs

Hello Eric, Got a 1986 Prostar 351PCM 1:1 trans top rpm 4300 at sea level with the stock 13x13 3 blade. Looking for a new prop. I am currently happy with the performance that this prop gives me. My main concern is not to lose any top speed on what I have right now.. What would you suggest?

Hello Eric, Need help please. I just purchased a 2001 MC Prostar 190 with a damaged prop and wish to buy a new one. Haven't run the boat except for brief test drive due to the vibration, so I don't have RPM info. Boat has power slot 1.5:1, 1-1/8" keyed shaft, MTR 330 HP engine. Current prop is not the original, it's an 13.7 x 17V HC OJ. I'm just getting back into slalom at age 51, and I'm out of shape so it will be "light" slalom. Really lost after researching this topic and the local pro is busy with Memorial Day customers. Thanks for your help. Bruce

Hi Eric,
I have a 97 Prostar 205 with an LT-1 engine and 1:1 transmission and 725 hours on the clock. It runs very well with great low down torque and tops out at 45mph at 4500 rpm with 7 adults in the boat. The current prop is an OJ Legend 4 blade 13x13 on a 1" shaft. We typically pull kneeboards (18mph/2000rpm), Wakeboards (18-20mph) and slalom at 30mph/3000rpm. I'm not wanting to barefoot.

I'm looking to keep a spare prop handy. I was thinking of ordering the same spec prop as a spare as the old one seems perfect.

Hey Eric,
I have a 2006 x star with MCX and am currently running the OJ 14.25X14.50. I run around 2500-3000k ballast plus people. The prop does ok but was wondering if there's something with a little better hole shot that wont take my rpms up much more. Thanks

Hey Eric,
I have a 2005 x45 with the 8.1L and looking for suggestion on a new prop. We wakeboard and surf. We run up to 3000# of ballast. The existing prop that was on it when I bought it was an oj 14.5x22. Running that much weight she works to get up on plan. Looking for a better out of the hole prop. Any suggestions?
Thanks
